A tutorial on how to correctly make and code a "linked_portal_door"

Adding a 'linked_ portal_door': ============================= - First, we have a black room and a white room.. Thee rooms are separated, but have a door-like cut-out in the wall... I have Red and Blue.. (See the 1st and 2nd pictures..) - Next, we'll have to place an entity called "linked_ portal_door" in these cut-outs.. (see the 3rd and 4th pictures) - Open the properties of these by double-click the first... edit the properties as in the 5th picture.. Have it the same in the other "linked_ portal_door", only change the name and linked partner. - Press apply, save the map and compile it... It should look like the 6th picture... **By that the tutorial is finished... I hope this was helpful! Please give feedback!**
